Complete operational breakdown of universal delimited credential strings (UID | Pass | 2FA | Cookie | Mail). Learn how to decode tokens and generate 6-digit authentication codes using 2fa.live in real-time.

Share:TelegramXLinkedIn

In professional digital asset and performance marketing operations, purchased advertising accounts and aged social profiles are rarely delivered as standard username and password pairs. To maximize security and enable automated multi-platform handling, credentials are provided as structured single-line strings delimited by the vertical bar ("|") pipe character.

1. Anatomy of an Enterprise Account Credential String

A standard full-pack advertising profile string is formatted in the following standardized sequence:

SYNTAX / DELIMITED FORMAT
UID | Password | 2FA Secret Key | Access Token | Cookie Session | Recovery Email | Email Password
NOLIMIT CREDENTIALS DECODING ARCHITECTURE (UNIVERSAL 7-SEGMENT STRING)
SEGMENT 1
UID / Account Identifier
15-digit unique numerical profile ID (e.g. 61577448402174) used as the master username for Facebook login.
SEGMENT 2
Master Password
Case-sensitive profile password. Do not alter during the initial 48-hour soak window.
SEGMENT 3
2FA 32-Character Base32 Key
Cryptographic seed (e.g. JBSWY3DPEHPK3PXP) used to generate time-based 6-digit OTPs via 2fa.live.
SEGMENT 4
Session Cookie Array (JSON / Base64)
Pre-authenticated session cookies including c_user and xs parameters for instant 1-click browser import.
SEGMENT 5
Recovery Mail & Mail Password
Clean Hotmail/Outlook/Gmail credentials used for recovery verification and billing notifications.

6. Recovery Email[email protected]Registered inbox associated with the profile for OTP verification.
7. Email PasswordSecPass#2026Access key for the linked recovery mailbox.

2. Step-by-Step: Logging in with Username, Password & 2FA.live

  1. Step 1: Open your dedicated browser profile (AdsPower, Dolphin Anty, or clean Chrome session) with your matching proxy active.
  2. Step 2: Navigate to facebook.com. Enter the numeric UID in the Email/Username field and paste the Password.
  3. Step 3: When prompted for the Two-Factor Authentication (2FA) 6-digit security code, open https://2fa.live in a new tab.
  4. Step 4: Copy the 32-character 2FA Secret Key from your delivered credentials and paste it into the 2fa.live input box, then click "Submit" (or press Enter).
  5. Step 5: Copy the generated 6-digit numeric code (e.g., 849201) and paste it into the platform prompt. Click "Trust this browser" to complete login.
PRO TIP & BEST PRACTICE

Always save your 32-character 2FA Secret Key in an authenticator app (such as Google Authenticator or 1Password) so you can generate fresh verification codes whenever requested in the future.
